IPC: B21D5/01
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To make a bending angle of the metal plate sharp with a set or several sets of rotation restraining implements and restore a metal contacting face of two bar-like slanted bottom dies to be automatically horizontal, without using the bottom dies of different sizes or shapes. SOLUTION: With reference to a metal plate 8 bent by pressurizing the metal plate 8 to a bottom die with an upper die 1, two units of bar-like bottom dies 2 (2a, 2b), cross section of which is semicircular, are manufactured as the bottom die. A rotation restraining implement 11 such as a spring is mounted at the top end part in a longitudinal direction of each concavely bent face 7 (7a, 7b) of the bar-like bottom die 2. Convexily vent faces 5 (5a, 5b) of two bar-like bottom dies 2 are loaded slidably and rotatably on a supporting element by providing with two concavely bent faces 7 having a groove 9 in between. The metal plate 8 is put on a metal contacting face of the two bar-like bottom dies 2 for pressurizing the metal plate 8 to the bottom die with the upper die 1.  This device has a metal bending mechanism for simultaneously bending a metal contacting face 6 (6a, 6b) of two bar-like bottom dies 2 by rotating inwardly against gravity of the rotation restraining implements 11.

Abstract: PROBLEM TO BE SOLVED: To prevent the faulty connection and the like of a connecting terminal and enable the proper discharge of a secondary battery, by so constituting a power supply that the power supply can be detached from an external load, and supplying power to charge the secondary battery to the external load by electromagnetic induction. SOLUTION: The oscillation circuit section 4a of a power supply converts a direct-current voltage output from a secondary battery 3 into a sine-wave voltage V1 at approx. 100kHz, and outputs it to the primary coil 4c of the power supply. The secondary coil 5b of a portable terminal device 5 converts an electromagnetic wave input from the primary coil 4c of the power supply into a voltage by electromagnetic induction, boosts the voltage, and outputs the boosted voltage from the secondary coil 5b to a control circuit section 5c. The control circuit section 5c smoothes the input boosted voltage to generate a smoothed voltage V2, controls the smoothed voltage V2 and thereby obtains a stable output voltage. The control circuit section 5c then supplies this voltage to an external load 5a. Thereby the faulty connection of a connecting terminal is prevented and the secondary battery 3 is properly discharged.

Title: Image formation system
Inventor: TAKESUE TOSHIHIRO
IPC: G03G21/00
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To shorten print time by outputting many print requests to a printer having a low jam rate. SOLUTION: It is checked whether these is the request of print or not (S10) and when these is any print request, the number of laser printers operable through a network at that time point is checked (S11). When three laser printers are operable and the print request shows 3000 sheets, for example, the print for 100 sheets is requested for each laser printer (S12). When jam occurs at any laser printer, however, print is delayed. Therefore, the number of sheets to be printed to be distributed is made different corresponding to the jam occurrence rate. The jam rate is (the number of jammed sheets)/(the number of normally printed sheets) and cumulatively counted for each printer. Because of such distribution, the number of sheets to be requested is decreased for the printer having frequent jam so that the rate of jam occurrence is statistically decreased.
